1 CHAPTER 40 INSTALLATION AND MAINTENANCE OF GAS-FUELED WATER AND SPACE HEATERS IN ALL PORTIONS OF DWELLINGS USED OR OCCUPIED FOR LIVING PURPOSES Subchapter A B C D Scope Departmental Procedure Where Heaters May be Used Installation of Gas-Fueled Heaters Subchapter A Scope Installation and Maintenance of Gas-Fueled Water and Space Heaters in all Portions of Dwellings Used or Occupied for Living Purposes. These rules shall govern the installation and maintenance of gas-fueled space and water heaters in the residence portions of multiple dwellings in the City of New York, including but not limited to the installation of such devices in multiple dwellings which are installed in lieu of centrally supplied heat and hot water under the provisions of and of the Administrative Code and in one and two family residences not heated by a central heating system. Subchapter B Departmental Procedure Applications and Plans. (a) Before commencing the installation of a gas-fueled space or water heater in a dwelling an application, as specified below must be filed in the borough office of the Department of Buildings where the installation is to be made, giving the address of the dwelling and all pertinent information required on the forms. (b) Applications shall be accepted only where gas appliances will be connected to flues in existing brick chimneys, and where no other venting or other work is required to be done. They shall not be accepted for installation of gas-fueled heaters in sleeping rooms. Applications shall clearly state the type of appliance to be installed, the floors, apartments and rooms in which they are to be placed, including the number of rooms in the apartment and the occupancy of each room, whether sleeping room or otherwise. They shall describe the condition of the chimney flue to be used and state whether the draft is satisfactory. If a gas meter is to be installed its location shall be given. (c) Where vent pipes are to be installed, or other work done in connection with the installation of gas-fueled heaters, an application shall be filed. It shall indicate the type of each such device, the floor on which, and the apartment and the occupancy of the room in which such appliance is to be installed, the material and dimensions of the vent pipe or flue, and the dimensions of the court or yard to which the exhaust vent will be carried. If a gas meter is to be installed, its location shall be shown. No plumbing specification sheet need be filed with such application. (d) Application for permits to install gas-fueled space and water heaters may be made separately or together on one application but each such application shall indicate that all apartments in the building will be provided with gas-fueled space and/or water heaters as the case may be. The location, type, make, and capacity of all such appliances previously installed or to be installed in a building shall be specified. If any of the appliances have been installed in multiple dwellings prior to December 9, 1955, which the owner desires to maintain, the necessary work to make them comply with these rules should be indicated. (e) An application may be filed by the owner of the premises, or his architect, engineer, contractor, plumber or other agent. If the application is not filed by the owner, an [sic] owner's authorization form also shall be filed Examination and Approval of Applications. (a) Applications, when filed, shall be processed in the usual manner and forwarded to the inspectors of

2 plumbing. (b) Applications calling for the installation of gas fueled space and water heaters shall be expedited and may be taken out of turn, except that they shall be processed in the order in which they were received. They shall be examined for compliance with these rules and all other laws and regulations applicable to such installations. If any chimney or metal stack is to be installed, examiners shall check such construction for compliance with subchapter 15 of Chapter 1 of Title 27 of the Administrative Code (Building Code). They shall require that the foundation shall be carried not less than four feet below the surface of the ground, and that the soil on which it is built to be not overloaded. They shall require that new chimneys be strapped to the existing walls. (c) Only applications calling for the installation of gas-fueled space or water heaters, approved by the Department of Buildings, specifying the make and model shall be approved. All such gas appliances shall be of types approved also by the American Gas Association. However, where an owner desires to continue to use any gas appliance installed in a multiple dwelling prior to December 9, 1955, clearly shows on the plan the data required by 40-11(f) and prominently marks the appliances that have not been approved by the Department of Health, the application may be conditionally approved pending the approval of the appliances by the Department of Health Commencement of Work. (a) It shall be unlawful to commence any construction for which an application has been filed until a permit for the proposed work has been issued by the borough superintendent, and it shall be unlawful to commence the installation of piping of any gas appliance until a registered plumber has filed a signed statement with the borough superintendent containing the address of said plumber and stating that he is duly authorized to proceed with the work. (b) The plumber shall notify in writing the borough superintendent of the Department of Buildings of the borough in which any gas-fueled space or water heater is to be installed, [sic] when such work is to begin and when it will be ready for operation and inspection Inspection of Gas-Fueled Space and Water Heaters. (a) Where an application has been filed it shall be the responsibility of the inspectors of plumbing to see that gasfueled space and water heaters are installed in dwellings, apartments and rooms where such heaters are permitted to be installed in lieu of central heat or supply of hot water. They shall see to it that the appliances are of types approved by the Department of Buildings and the American Gas Association, and are installed in compliance with these rules. (b) An application covering the installation of these appliances in dwellings shall be forwarded directly to the plumbing inspectors when approved as a permit. The installation of such appliances including Type B and other gas vents, but not chimneys, shall be inspected by inspectors of plumbing. If an application does not call for construction of a masonry or metal chimney, it shall be reported as completed, by the plumbing inspector, provided the work was satisfactory with a note on his report "no structural work." (c) If the application calls for the erection of a masonry or metal chimney, it shall be forwarded by the plumbing inspector to the construction inspector as soon as the plumbing inspector has found the installation of these gas appliances and vent connections satisfactory. The construction inspector shall report such an application completed if the construction of the chimney has been satisfactorily performed Issuing Approvals. (a) A gas-fueled space or water heater installed after December 18, 1957, and a gas-fueled space heater installed prior to that date, in the residence portion of a multiple dwelling and installed after October 1, 1964, in one and two family dwellings, shall be approved by the Department of Buildings only if it is of a type approved by the Department of Buildings and the American Gas Association, and if it has been installed in compliance with these rules. A gas-fueled water heater installed in a multiple dwelling prior to December 18, 1957, and in a one or two family dwelling prior to October 1, 1964 shall be approved by this department only after it has been made to comply with all the requirements of these rules. The certification of approval of type of appliance by the

3 Department of Buildings of such water heaters shall be attached to the application. (b) An application which has been filed to cover the installation of only gas-fueled space heaters or only gasfueled water heaters shall be reported as being satisfactory completed only if all apartments in the building have been provided with either space or water heaters as the particular application specified. If an application calls for the installation of both space heaters and water heaters it shall be reported as being satisfactorily completed only if all apartments in the building have been provided with both space heaters and water heaters. Nor shall any application be reported as being satisfactorily completed unless all new appliances have been installed in compliance with these rules and all existing appliances have been made to conform with them. (c) When the plumbing section signs off, as satisfactorily completed, an application which provides for the installation of gas-fueled space heaters in all apartments of a multiple dwelling, including the apartments where gas-fueled space heaters may have been installed prior to December 18, 1957, they shall make a list of such premises and send a copy of the list to the Department of Housing Preservation and Development. Where water heaters also have been satisfactorily installed, that fact shall be noted on the list. The list shall contain the premises and the application number under which the appliances have been installed, and shall be forwarded weekly. Subchapter C Where Heaters May be Used Substitution for Central Heating or Hot Water Supply.
